This is the remarkable moment a brave member of the public confronts Ali Sonboly, the Munich terror suspect, from a balcony in a video that was filmed on Friday during his murderous rampage at a McDonald's restuarant.

The cell-phone video posted online showed the suspect dressed in black standing on a rooftop parking area of the mall yelling back and forth, saying at one point "I'm German" and eventually firing shots.

The conversation has been translated from German into English by Reddit users.

Balcony man: 'You fucking a*****e you...'

Gunman: 'Because of you I was bullied for 7 years...'

Balcony man: 'You w****r you. you're a w****r'

Gunman: '...and now I have to buy a gun to shoot you'

Balcony man: 'A gun! F**k off! Your head should be cut off you a*****e'

The gunman and balcony man begin shouting at each other.

Balcony man (apparently to people filming): 'He's got a gun here the guy has one'

Unseen voice: 'F*****g Turks!'

Balcony man: 'F*****g foreigner'

Balcony man to someone else: 'Ey! He's got a gun! He has loaded his gun. Get the cops here. He's walking around here the w****r!'

Munich police chief Hubertus Andrae told a news conference early Saturday that the suspect was a dual citizen from Munich and his motive was still "fully unclear." He said it was too early to label the attack an act of terrorism; earlier police said they had no indication of Islamic extremism.

"The question of terrorism or a rampage is tied to motive, and we don't know the motive," Andrae said.

Police gave a "cautious all clear" in the pre-dawn hours Saturday, more than seven hours after the attack began and brought much of the city to a standstill as all public transit systems were shut down amid a massive manhunt. They said a body found near the scene was that of the shooter and he appeared to have acted alone and killed himself as he fled.

Andrae said the suspect's body was found about 2 1/2 hours after the attack and was determined to be the shooter based on witness statements and closed circuit television footage of the attack. The shooter, whose name wasn't released, was not previously known to police and there was no evidence of any links to terrorist organizations, Andrae said.

"We can't question the suspect so this is all a little more difficult," he said.
